A huge TV audience is expected to tune in on Sunday night to catch the end of a gripping thriller.
Remember Me, starring Michael Palin, has been a huge hit - especially with people in Huddersfield, where much of it was filmed.
And that has delighted Slaithwaite writer Gwyneth Hughes who came up with the chilling tale.
She explained in a BBC blog she had always been drawn to mystery.
“I live in Yorkshire, so naturally I tend to want to set my stories here. But particularly for Remember Me, the big skies and deserted landscapes seemed very suitable!
“I love spending time in Scarborough, so once I had the idea that the song Scarborough Fair might play a part in the drama, it was a no-brainer to go to the seaside for filming.

“As a viewer, I always get really annoyed if actors’ accents are all over the place, which is reason enough to cast northern actors for Remember Me. But it’s also great to get people who really understand the landscape and the way of life here, so that the film stands a chance of being really true to itself, and can offer a real sense of place.
“I didn’t have anybody in mind to play the central character of Tom Parfitt, but the minute Michael Palin’s name came up, I was dancing round the house shouting down the phone: “Yes! Yes!”
“Michael signed up to play Tom on the strength of reading the first episode - I hadn’t then written the others! So my initial joy was soon followed up by anxiety about what I was going to put in the next two episodes.
“I always like to have a very wide range of characters in my stories. Old and young, male and female, English and Asian. And this project is no different. The care home came into the story because I wanted Tom to decide to leave his own home to get away from his memories. It was the natural place to send him, and give him a brief sense of safety”.
Ms Hughes said she was brought up on the Brothers Grimm, so a good scary story had always held my attention.

“All ghost stories have to emerge from a sense of loss and loneliness, I think, and all these characters have lost something very precious. Remember Me has a contemporary setting, and the emotional and family relationships I explore come very much from our own world. So I think I’ve been trying to marry an old-fashioned ghost story with a very contemporary drama of character.
“I can’t really cope with stories where nobody dies, because I can’t work out why it’s important. I really don’t much like films where everyone sits about and talks and nothing much happens! I like the stakes to be high in a story.
“A lot of crime drama can be thin on characterisation and unnecessarily brutal, and I can’t be doing with that kind of thing. But a good mystery, whether crime or otherwise, really holds your attention and takes your mind off your own troubles. It’s the best kind of escapism, to me”.
